These prices are from the 1998 catalouges from all three suppliers.
RP1 is not available from any of the above suppliers. You can either use 8 4K7 resistors and solder a wire to the top of each or get SIP resistors from RS Compnents in packs of 5.
If getting all components from these suppliers the price will range from $47AUS to $77AUS (without ZIF socket or PCB) depending on where you buy the parts. If you wish to save money you can solder straight to the PCB and not use the SIP plug and Header. Using a standard DB25 instead of an IDC version will also save a few dollars. If you also allready have a suitable power supply the rest of the parts will only cost about $30AUS
